Read the first passage from "the tell-tale heart” that karishma read.

i had my head in, and was about to open the lantern, when my thumb slipped upon the tin fastening, and the old man sprang up in bed, crying out—"who's there? "

after reading the passage, karishma predicted that the narrator would get caught by the old man.

now read the second passage that karishma read.

i kept quite still and said nothing. for a whole hour i did not move a muscle, and in the meantime i did not hear him lie down. he was still sitting up in the bed listening; —just as i have done, night after night, hearkening to the death watches in the wall.

the most logical revision for karishma to make to her prediction is that the narrator

gives up his plan to murder the old man.
comes back another night to murder the old man.
continues with his plan to murder the old man.
eventually admits his presence to the old man.
